I think it will be less work for me to buy 2-540s from Atco and put them in,then go with Bravos. If I put new drives it would be Konrads. What size prop do you think I would need for 600 hp with Trs drives? I have 24 Bravos now that spin 5200 rpm.

26 or 28 if your old power was 450 to 500 and what did you peak at with old compared to new my 650hp motor red line was 6000 so propped it for 5700 to 5800.

Brian,

I'd just leave things alone. You never run over 50 mph.
